Amendment Description Restatement BackgroundIn connection with the preparation and review of the Richtech Robotics Inc. (the “Company”) financial statements for the quarter ended March 31, 2026, management identified errors in the Company’s previously issued financial statements for the fiscal year ended September 30, 2024, the interim periods ended December 31, 2024, March 31, 2025, June 30, 2025 during fiscal year 2025, the fiscal year ended September 30, 2025, and the quarter ended December 31, 2025 (collectively, the “Affected Financial Statements”). As a result of these findings, on June 9, 2026, the audit committee, in consultation with the Company’s management, determined that the Affected Financial Statements should no longer be relied upon.Additionally, the Company determined that any previously issued or filed reports, including financial statements, and other communications describing the Affected Financial Statements and related financial information should no longer be relied upon.The identified errors primarily relate to the Company’s accounting for warrants issued in connection with equity financing transactions, employee and nonemployee stock-based compensation arrangements, transactions executed under a Standby Equity Purchase Agreement dated as of February 15, 2024, with YA II PN, Ltd. (“SEPA”) and related convertible notes payable, and the classification of certain property and equipment. Specifically, the Company did not appropriately evaluate and record certain warrants, including determining the proper classification between equity, mezzanine equity, and liabilities, and did not appropriately recognize fair value at issuance and in subsequent periods. In addition, certain stock-based compensation awards, including non-employee awards issued in the form of warrants requiring mezzanine equity classification and employe awards issued in the form of restricted stock awards, were improperly accounted for, resulting in misstatements of accrued expenses and other payables, mezzanine equity, additional paid-in capital and compensation expense. The Company also identified errors in its accounting for SEPA-related transactions and convertible notes, including incomplete recognition and misclassification of associated balances and related income statement impacts. Further, certain assets were incorrectly classified as depreciable assets, resulting in overstated depreciation expense. The Company also identified errors related to revenue recognition, including adjustments to decrease revenue and increase deferred revenue, as well as related adjustments to increase inventory and decrease cost of goods sold. Additionally, certain intangible assets were not appropriately accounted for due to revisions to their estimated useful lives, resulting in shorter amortization periods (collectively, the “Errors”).Restatement of Previously Issued Financial StatementsThis Amendment to the Quarterly Report on Form 10-Q/A (“Form 10-Q/A”) for the three months ended December 31, 2025 includes unaudited condensed consolidated financial statements as of and for the three months ended December 31, 2025. The Company has restated certain information within this Form 10-Q/A, including the unaudited condensed consolidated financial statements for the three months ended December 31, 2025 and 2024 and the related comparative prior period financial information for the fiscal years ended September 30, 2025 and 2024.In addition to the restatement adjustments described above, the Company also evaluated other identified errors that were determined to be immaterial, individually and in the aggregate, to the previously issued financial statements for the impacted periods. Such items have been corrected in the period presented in this Form 10-Q/A.The Company has also issued an amendment to its previously issued Annual Report on Form 10-K for the fiscal year ended September 30, 2025 to reflect the correction of these errors and the related restatement of prior period financial information and interim periods for the fiscal year ended September 30, 2025.The Company evaluated the identified misstatements in accordance with Accounting Standards Codification (“ASC”) 250, Accounting Changes and Error Corrections, and SEC Staff Accounting Bulletin No. 99 (“SAB 99”), considering both quantitative and qualitative factors. Based on this evaluation, the Company concluded that the errors were material to the previously issued financial statements for the impacted periods. Accordingly, the Company has restated the affected financial statements to reflect correction of these errors.See Note 2, Restatement of Previously Issued Financial Statements, to the unaudited condensed consolidated financial statements included in Part I, Item 1 of this Form 10-Q/A for additional information regarding the restatement, including a description of the errors and the impact on the Company’s consolidated financial statements and related disclosures.Except as described above, no other information included in the original Form 10-Q is being amended or updated by this Form 10-Q/A and, other than as described herein, this Form 10-Q/A does not purport to reflect any information or events subsequent to the original Form 10-Q. This Form 10-Q/A continues to describe the conditions as of the date of the original Form 10-Q and, except as expressly contained herein, we have not updated, modified or supplemented the disclosures contained in the original Form 10-Q.
